2 Clips or sockets 18 are secured to the outer faces ofthe end walls and carry the handles 19 bymeans of which the pan may be handled or" as sho wn Figure 1 single handle 17' is connected to the rear wall and 1s known in the art as'a Johnson bar.

. The scraper is provided witha' tongue 20 whic-h issupported at its rear end from a tion depending hanger brackets 22 through These hounds 23 extend forwardly and nently connected with the tongue andv have their rear portions curved downwardly and pivotallyv connected with the end walls of with the end walls of the pan. by entending throughsets of openings-formed'in the end the: panthrough thellmedium of brackets2et.

Thisv chain may be constructed of the "same size links {throughout its length or it may be provided with. relatively. small links for the greater number of-relativelylarge links at=its for.

When this-trigger shaft fro V turnedin,onetdirection, the slack in'the cable will-betaken upon and the: pan will be tilted forwardly slightly thus bringing the forward edge of the-cutting blade intooperi ative. engagement with the ground; When thepan is turnecl-to the dumping position it is desired to retainthe scraping blade in -spa'ced relation to the" ground andin order to-do this, :there has been provided-shoes which will be positioned upon-opposite ends or sides of "the pan and maybe constructed either as shown in Figure '5 or as shown in Figure-6. In the form-shown in Figure 5 I and shown in place upon the pan in Figu'res 1; 2, and- 3, the s'hoes are formed from "plates- 32 havingv their outer end portions .bent to provide flanges or runners 33 and .the inner endportion of said plates are justedf .What :is claimed is:

engagement with the ground. The draft animals will be driven forwardly and as.

theymove forwardly the earth will be taken up'b y-the panQ When the pan is filled the triggersha-ft will be rotated and returned to its'initial-position .The pan will then rest upon the, curved bottom and the :pan can be drawn over the ground without. danthe trigger, shaft will be rotated .to draw .up'on thejchain thus causing the pan to be tilted forwardly and bring theforward edge of the digging blade 16 intoY'operative ger of the contents being spilled. By .pio-

viding; this construction; the panwill be selfyfilling and there will be no danger of the operator being struck by a,lever.- or

handle if'the cutting edge of the blade should strike a rock or other obstruction;

There is also no danger of the' pan being turned completely; over and striking the draft animals and thus causinginjury to them which -might make necessary to kill the animals. When'thepoint is reached where the pan is to be dumped, it 1 is only necessary to swing the pan forwardlyso that it will turn and rest upon therunners of the shoes; After the pan has been dumped, the

scraperwill bedrawn back to the point ofy filling and as it passesover the ground the pan will; beheld in spaced rel'ationto thev ground, and trash prevented from collecting under the pan This pan can be= used in close corners'fand' in any kind ofground either level or hilly and will very elliciently do the work of the prior patents referred to without dangerto men or animals.

A scraper comprising? a-pan having side walls and-open at its'forward end, shoes connected wlth the side wallsyand a draft appliance connected with the side walls, each shoe comprising a plate fitting-against the side wall and'having its forward portion extending forwardly of the side wall and having a flange extending to one. side and curved longitudinally to provide a runner positioned in frontof the side wall and vertically curved, the rear portion of the plate being provided with arms fextendjustably connected to the side walls of the pan, a handle connected to the pan, and

plates adjustably secured to the side walls of the an and-projecting forwardly of the fronte ges of said side wallsand having their 1 forward edges bent laterally and curved longitudinally to provide dumping runners. I
